Abstract

Tannic acid(TA)was immobilized onto a glycidyl methacrylate-grafted fiber. The TA-immobilized fiber(TA fiber)with a TA content of 25 % was applicable to the collection of vanadium(V)from the spring water of Mt. Fuji. The contact in a batch mode for 1 day of the 1 g TA fiber with 1 L spring water containing V at a concentration of 58 μg-V/L led to collection of 70 %. The amount of V adsorbed onto the TA fiber was quantitatively eluted with 0.5 M hydrochloric acid. In addition, the amount of V adsorbed remained constant after the third cycle of repeated adsorption and elution of V.
